Older cottages in Olde Towne and many homes elevated in the years after Hurricane Katrina sit on piers or raised foundations. That height keeps the living floor dry in most floods, but water still pools underneath from rain, rising bayous and leaking pipes. A wet crawl space feeds moisture into the subfloor and the air of the house for weeks.
What a wet crawl space does to a house
Water under the floor evaporates into the crawl space air, and that damp air rises through the subfloor. Fiberglass insulation between the joists soaks up water and sags. Wood joists and subfloor absorb moisture and can cup the hardwood above. Left alone in humid weather, the space stays wet for weeks.
- Sagging or fallen insulation between the joists
- Cupped wood floors or a musty smell inside
- Standing water on the vapor barrier or the soil
Pumping out and drying under the house
The extraction crew pumps standing water off the vapor barrier or the soil. Soaked insulation and torn or flooded vapor barrier come out. The drying team then runs air movers and a dehumidifier in the crawl space, closing vents if needed so the equipment is not fighting outside air, and takes readings on joists and subfloor until they reach the goal.
- Standing water pumped out
- Wet insulation and damaged vapor barrier removed
- Joists and subfloor dried, with readings
Flood water under the house
Water that came in from outside is Category 3, so wet insulation is discarded and surfaces are cleaned and treated before drying. FloodSmart.gov explains how flood policies treat areas below the lowest floor, and Ready.gov flood safety advice covers safe entry after a flood.

Questions
Crawl Space Water Removal questions, answered
Why is there water under my raised house?
Heavy rain, a rising bayou, poor grading or a leaking pipe can all put water under a raised floor. The tech finds the source before drying starts.
Does wet crawl space insulation have to be replaced?
Yes, if it soaked. Wet fiberglass sags, holds water against the joists and stops insulating.
Can water under the house damage the floors?
Yes. Moisture rises into the subfloor and can cup hardwood and loosen tile above. Drying the crawl space protects the floors.
How long does a crawl space take to dry?
Usually three to seven days with equipment running, longer after flood water or in very humid weather.
Is crawl space water covered by insurance?
A sudden pipe leak is often covered after the deductible. Flood water under a house falls under flood coverage, which limits what it pays below the lowest floor. Coverage depends on your policy, so check with your own insurer.
Should crawl space vents stay open to dry it out?
Not during drying in humid weather. Outside air carries moisture in, so the drying team often closes vents while the dehumidifier works.
